Effect of intramolecular crosslinker properties on the mechanochemical fragmentation of covalently folded polymers was written by Levy, Avishai;Goldstein, Hadar;Brenman, Dolev;Diesendruck, Charles E.. And the article was included in Journal of Polymer Science (Hoboken, NJ, United States) in 2020.Reference of 4074-88-8 This article mentions the following:
The mechanochem. stability of polymers in solution is enhanced if the chains are covalently folded. Under shear forces, the addnl. bonds absorb mech. energy and inhibit unfolding, and as a result, slow down fragmentation. However, not all crosslinkers are equal in terms of their properties (length, strength, etc.). In order to understand the role of these added bonds in the polymers’ stability under mech. stress, a thorough study compares the rate of mechanochem. on single-chain polymer nanoparticles which have been folded with crosslinkers with different lengths, strengths, positioning, and valencies. The usage of bonds with different mech. strengths in the crosslinkers was found to be the most powerful way to change the mechanochem. fragmentation rate. In addition, positioning and valency also play significant role in the mech. stabilization mechanism. In the experiment, the researchers used many compounds, for example, Diethyleneglycoldiacrylate (cas: 4074-88-8Reference of 4074-88-8).
Diethyleneglycoldiacrylate (cas: 4074-88-8) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. The most common reactions of alcohols can be classified as oxidation, dehydration, substitution, esterification, and reactions of alkoxides.Reference of 4074-88-8
